@Steve Walmsley have you tried or even played MANO (Modern Air Naval Operations) to see how they deal with the display of unit names and vectors? It can be very rapidly a mess, display wise and I think they did a few things right to de-obfuscate/unscramble display. I'm basing my observations on some screenshots, I did not play the game. But for example at a certain zoom level, individuals ships are replaced by a TF icon, and you can tooltip it. Will Aurora C# supports tooltip on the main map?
